The Interaction Of Multiple Convection Zones In A-type Stars

TL;DR

This paper investigates how multiple convection zones in A-type stars interact through stable regions, using numerical simulations to understand their potential disjointness and implications for stellar mixing.

Contribution

The study provides new numerical simulation results analyzing the interaction of multiple convection zones in A-type stars based on their separation distance.

Findings

Interaction likelihood depends on separation distance

Convection zones can influence each other through stable regions

Impacts mixing and transport processes in stars

Abstract

A-type stars have a complex internal structure with the possibility of multiple convection zones. If not sufficiently separated, such zones will interact through the convectively stable regions that lie between them. It is therefore of interest to ask whether the typical conditions that exist within such stars are such that these convections zones can ever be considered as disjoint. In this paper we present results from numerical simulations that help in understanding how increasing the distance between the convectively unstable regions are likely to interact through the stable region that separates them. This has profound implications for mixing and transport within these stars.
